Hi Richard:
Thanks you very much, that help me a lot . there is a doubt need to be
sure:
MY HW doesn't support Sync and Delay_req at the same time. But it could be
changed with setting ptp event id by register.
Does it help ?
PTP Message ID Register Description
PTP Message ID
This field determines the PTP MessageID (or PTP Control for V1) field
in the
incoming PTP Packets to be selected for Timestamping. The software can
use
this field to timestamp either the SYNC or DELAY_REQ Packets
based on
whether the Device is Slave or Master respectively

To be useful, the HW + driver must support Sync and Delay_req at the same time.

No. And you can't get very far with only Sync, for example.

Talk to your HW developers, and tell them to fix their stuff.
Thanks,
Richard
